老师留个小作业,用EXCEL做不同lambda(np)的泊松分布图,这里分别用EXCEL,Python,MATLAB和R简单画一下. 1. EXCEL 运用EXCEL统计学公式,POISSON,算出各个数据,作图.资料参考这里. =POISSON.DIST(B$1,$A2,0) 注意这里绝对引用的方式,写完公式之后,直接上下左右拖动鼠标即可自动填充.之后插入图表.如下. 2.Python 这里stats.poisson.pmf中的pmf是probability mass function(概率质…

Poisson Distribution Given a Poisson process, the probability of obtaining exactly successes in trials is given by the limit of a binomial distribution (1) Viewing the distribution as a function of the expected number of successes (2) instead of the…

PDF version PMF A discrete random variable $X$ is said to have a Poisson distribution with parameter $\lambda > 0$, if the probability mass function of $X$ is given by $$f(x; \lambda) = \Pr(X=x) = e^{-\lambda}{\lambda^x\over x!}$$ for $x=0, 1, 2, \cd…
